But many technologies that later came to be considered essential parts of modern life began their life as unnecessary technical baubles. For example, in 1970, the first consumer VCR prototype was unveiled at CES, a technology previously only needed by television studios. The home VCR then started the home-viewing and -recording revolution, leading to a critical U.S. Supreme Court decision regarding copyright, and laying the groundwork for YouTube and Netflix. Even when a technology goes nowhere--3D TV glasses anyone?--looking at widgets, gizmos, and novelties can still provide a unique window into larger technological and cultural trends.
